EARLIER DAX Function Not recommended
Returns the value in the column prior to the specified number of table scans (default is 1).
Syntax
| Parameter | Attributes | Description |
|---|---|---|
| ColumnName |
The column that contains the desired value. |
|
| Number | Optional |
The number of table scan. |
Return values
The current value of row, from ColumnName, at Number of outer evaluation passes.
Remarks
EARLIER succeeds if there is a row context prior to the beginning of the table scan. Otherwise it returns an error.
It is recommended using variable (VAR) saving the value when it is still accessible, before a new row context hides the required row context to access the desired value.
